What it meansThe US Department of Agriculture's national organic standard. The green-and-white seal is the legal mark for any food sold as 'organic' in the United States.The international umbrella body for the organic movement. Not a product label — IFOAM accredits other certifiers worldwide via the IFOAM Family of Standards. If a cert is 'IFOAM-accredited' it has been benchmarked to a globally consistent baseline.Vottunarstofan Tún is Iceland's only accredited organic certifier. Accredited by MAST (Matvælastofnun) under the EU 2018/848-equivalent Icelandic standard, so a Tún-certified product is also recognised as EU-organic.

Guarantees
  • At least 95% of ingredients are certified organic (the '100% Organic' variant requires every ingredient).
  • No synthetic pesticides, no synthetic fertilizers, no GMOs, no sewage sludge, no irradiation.
  • Annual on-site inspection by a USDA-accredited certifier.
  • Residue testing on at least 5% of certified operations each year.
  • Accredited certifiers meet the IFOAM Norms and the IFOAM Family of Standards.
  • Independent peer review of certifier governance, inspection rigor, and conflict-of-interest controls.
  • ≥95% organic ingredients per EU rules.
  • No synthetic pesticides, no GMOs.
  • Annual on-site inspection.
  • Animal welfare standards (outdoor / pasture access, geothermally-warmed greenhouse compatibility for vegetables).
Does NOT
  • Doesn't certify nutrition, taste, or animal welfare specifically (separate marks like AWA cover welfare).
  • Doesn't guarantee local production — a 'USDA Organic' product can be grown anywhere with an accredited inspector.
  • Does NOT certify products directly — only certifiers. Look for the underlying national / private mark on the package.
  • There aren't many Tún-certified operations (~120–160) — coverage in the Icelandic market is narrower than in the EU mainland.
